Delayed Argon Administration Provides Robust Protection Against Cardiac Arrest-Induced Neurological Damage
Introduction Argon at a dosage of 70 % is neuroprotective, when given 1 h after cardiac arrest (CA) in rats. We investigated if a neuroprotective effect of argon would also be observed, when administration was delayed. Methods Twenty-four male Sprague–Dawley rats, weighing between 400 and 500 g were...

| 520 | |a Introduction Argon at a dosage of 70 % is neuroprotective, when given 1 h after cardiac arrest (CA) in rats. We investigated if a neuroprotective effect of argon would also be observed, when administration was delayed. Methods Twenty-four male Sprague–Dawley rats, weighing between 400 and 500 g were subjected to 7 min of CA and 3 min of cardiopulmonary resuscitation. Animals were randomized to receive either 1 h of 70 % argon ventilation 1 h (n = 8) or 3 h (n = 8) after return of spontaneous circulation or no argon treatment (n = 8). For all animals, a neurological deficit score (NDS) was calculated daily for 7 days following the experiment. On day 8, rats were re-anesthetized and transcardially perfused before brains were harvested for histopathological analyses. Results All animals survived. Control animals exhibited severe neurologic dysfunction at all time points as measured with the NDS. Argon-treated animals showed significant improvements in the NDS through all postoperative days, even when argon administration was delayed for 3 h. This was paralleled by a significant reduction in the neuronal damage index in the neocortex and the hippocampal CA 3/4 region in argon-treated animals, regardless of the timing of argon administration. However, animals of the delayed argon administration group additionally showed significant reductions in the basal ganglia in comparison with control animals. Conclusion Our study demonstrates that a 1-h application of argon provided a significant reduction in histopathological damage, associated with a marked improvement in functional neurologic recovery even when treatment was delayed for 3 h. This is highly significant with regard to clinical situations, where argon treatment cannot be provided timely. | ||

We investigated if a neuroprotective effect of argon would also be observed, when administration was delayed. Methods Twenty-four male Sprague–Dawley rats, weighing between 400 and 500 g were subjected to 7 min of CA and 3 min of cardiopulmonary resuscitation. Animals were randomized to receive either 1 h of 70 % argon ventilation 1 h (n = 8) or 3 h (n = 8) after return of spontaneous circulation or no argon treatment (n = 8). For all animals, a neurological deficit score (NDS) was calculated daily for 7 days following the experiment. On day 8, rats were re-anesthetized and transcardially perfused before brains were harvested for histopathological analyses. Results All animals survived. Control animals exhibited severe neurologic dysfunction at all time points as measured with the NDS. Argon-treated animals showed significant improvements in the NDS through all postoperative days, even when argon administration was delayed for 3 h. This was paralleled by a significant reduction in the neuronal damage index in the neocortex and the hippocampal CA 3/4 region in argon-treated animals, regardless of the timing of argon administration. However, animals of the delayed argon administration group additionally showed significant reductions in the basal ganglia in comparison with control animals. Conclusion Our study demonstrates that a 1-h application of argon provided a significant reduction in histopathological damage, associated with a marked improvement in functional neurologic recovery even when treatment was delayed for 3 h. This is highly significant with regard to clinical situations, where argon treatment cannot be provided timely.

We investigated if a neuroprotective effect of argon would also be observed, when administration was delayed. Methods Twenty-four male Sprague–Dawley rats, weighing between 400 and 500 g were subjected to 7 min of CA and 3 min of cardiopulmonary resuscitation. Animals were randomized to receive either 1 h of 70 % argon ventilation 1 h (n = 8) or 3 h (n = 8) after return of spontaneous circulation or no argon treatment (n = 8). For all animals, a neurological deficit score (NDS) was calculated daily for 7 days following the experiment. On day 8, rats were re-anesthetized and transcardially perfused before brains were harvested for histopathological analyses. Results All animals survived. Control animals exhibited severe neurologic dysfunction at all time points as measured with the NDS. Argon-treated animals showed significant improvements in the NDS through all postoperative days, even when argon administration was delayed for 3 h. This was paralleled by a significant reduction in the neuronal damage index in the neocortex and the hippocampal CA 3/4 region in argon-treated animals, regardless of the timing of argon administration. However, animals of the delayed argon administration group additionally showed significant reductions in the basal ganglia in comparison with control animals. Conclusion Our study demonstrates that a 1-h application of argon provided a significant reduction in histopathological damage, associated with a marked improvement in functional neurologic recovery even when treatment was delayed for 3 h. This is highly significant with regard to clinical situations, where argon treatment cannot be provided timely.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cardiopulmonary resuscitation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hypoxia–ischemia, Brain</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Reperfusion injury</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Noble gases</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Argon</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Neuroprotective agents</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kurnaz, Pinar</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bleilevens, Christian</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Derwall, Matthias</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Weis, Joachim</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Nolte, Kay</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Rossaint, Rolf</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fries, Michael</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Neurocritical care</subfield><subfield code="d">New York, NY : Springer, 2004</subfield><subfield code="g">22(2014), 1 vom: 01.

Delayed Argon Administration Provides Robust Protection Against Cardiac Arrest-Induced Neurological Damage |
| abstract |
Introduction Argon at a dosage of 70 % is neuroprotective, when given 1 h after cardiac arrest (CA) in rats. We investigated if a neuroprotective effect of argon would also be observed, when administration was delayed. Methods Twenty-four male Sprague–Dawley rats, weighing between 400 and 500 g were subjected to 7 min of CA and 3 min of cardiopulmonary resuscitation. Animals were randomized to receive either 1 h of 70 % argon ventilation 1 h (n = 8) or 3 h (n = 8) after return of spontaneous circulation or no argon treatment (n = 8). For all animals, a neurological deficit score (NDS) was calculated daily for 7 days following the experiment. On day 8, rats were re-anesthetized and transcardially perfused before brains were harvested for histopathological analyses. Results All animals survived. Control animals exhibited severe neurologic dysfunction at all time points as measured with the NDS. Argon-treated animals showed significant improvements in the NDS through all postoperative days, even when argon administration was delayed for 3 h. This was paralleled by a significant reduction in the neuronal damage index in the neocortex and the hippocampal CA 3/4 region in argon-treated animals, regardless of the timing of argon administration. However, animals of the delayed argon administration group additionally showed significant reductions in the basal ganglia in comparison with control animals. Conclusion Our study demonstrates that a 1-h application of argon provided a significant reduction in histopathological damage, associated with a marked improvement in functional neurologic recovery even when treatment was delayed for 3 h. This is highly significant with regard to clinical situations, where argon treatment cannot be provided timely. |
